GREENS Mobile App is a free Android application developed by the Environmental Protection Department (EPD) of the Government of the Hong Kong Special Administrative Region. The app is designed to facilitate the public's participation in the GREEN$ Electronic Participation Incentive Scheme (ePIS) through smartphones. Members of the ePIS can earn GREEN$ for the redemption of gift items by submitting recyclables at Recycling Stations, Recycling Stores, and Recycling Spots for clean recycling.

The app is simple and easy to navigate, making it convenient for users to access the ePIS on the go. The app's interface is user-friendly, with clear and concise instructions for users to follow. GREENS Mobile App also provides users with a list of nearby Recycling Points, allowing them to easily locate the nearest recycling point for recyclable submission. Overall, the app is a great initiative by EPD to encourage recycling and raise environmental awareness among the public.
